Constructor & Destructor Documentation

IlvScript::IlvScript

(

IlvScriptContext *

context

)

Constructor.

The constructor initializes a new empty IlvScript.

Parameters

context

The script context where this script will be stored.

IlvScript::IlvScript	(	IlvScriptContext *	context,
		istream &	,
		const char *	filename = 0,
		const char *	name = 0
	)

Constructor.

The constructor initializes a new IlvScript that is read from a stream.

Parameters

context	The script context where this script will be stored.
stream	The input stream from which the script is read.
filename	The file name of this stream, or 0 if the stream has no associated file. This is used in error messages for easier correction.
name	The name of that script, or 0 if you do not want this script to have a name. Named scripts can be retrieved easily from a script context. This string is copied internally.

IlvScript::IlvScript	(	IlvScriptContext *	context,
		const char *	contents,
		const char *	name = 0,
		const char *	path = 0
	)

Constructor.

The constructor initializes a new IlvScript that is created from a string.

Parameters

context	The script context where this script will be stored.
contents	The string from which the script is created. This must be a 0 terminated string with valid scripting contents. This string is copied internally.
name	The name of that script, or 0 if you do not want this script to have a name. Named scripts can be retrieved easily from a script context. This string is copied internally.
path	A path that can identify the script, or 0 if the script has no associated path. This is used in error messages for easier correction. This string is copied internally.

IlvScript::IlvScript	(	IlvScriptContext *	context,
		IlUInt	nLines,
		const char *const *	lines,
		const char *	name = 0,
		const char *	path = 0
	)

Constructor.

The constructor initializes a new IlvScript that is created from an array of strings (typically, an array of lines).

Parameters

context	The script context where this script will be stored.
nLines	The number of strings in the array lines.
lines	The array of at least nLines lines from which the script is created. Each string in the array must be a 0 terminated string, and the concatenation of all the strings should be a valid scripting contents. This array and all the strings it holds are copied internally.
name	The name of that script, or 0 if you do not want this script to have a name. Named scripts can be retrieved easily from a script context. This string is copied internally.
path	A path that can identify the script, or 0 if the script has no associated path. This is used in error messages for easier correction. This string is copied internally.

virtual IlvScript::~IlvScript ( )

virtual

Destructor.

Releases the memory used by the script.

Member Function Documentation

const char* IlvScript::getContents

(

)

const

Gets the script contents.

This member function should be used only when the script is of the type IlvInlineScript.

Returns

the contents of the script as a string. The returned string must not be modified or deleted by the user.

const char* const* IlvScript::getContentsArray

(

IlUInt &

nLines

)

const

Gets the script contents.

Parameters

nLines

The size of the returned array (that is, usually, the number of lines in the script).

Returns

The contents of the script as an array of strings. This member function should be used only if the script is of the type IlvInlineScript. The returned array and its contents must not be modified or deleted by the user.

IlvScriptContext* IlvScript::getContext

(

)

const

Gets the script context.

Returns

the script context of this script.

IlvScriptLanguage* IlvScript::getLanguage

(

)

const

Gets the scripting language.

Returns

The scripting language used by this script.

const IlSymbol* IlvScript::getLanguageName

(

)

const

Gets the name of the scripting language.

Returns

The name of the scripting language used in this script. This method is useful when you do not want to link with an interpreter, but still want to manipulate script languages, script contexts and scripts.

const char* IlvScript::getName

(

)

const

Gets the script name.

Returns

The name of the script or 0 if the script has no name. The returned string must not be deleted or modified by the user.

const char* IlvScript::getPathName

(

)

const

Gets the script path name.

Returns

The path name of the script, or 0 if it has none. This member function should be used only if the script is of the type IlvLinkedScript. The returned string must not be deleted or modified by the user.

IlvScriptType IlvScript::getType

(

)

const

Gets the script type.

Returns

The type of this script. Scripts of the type IlvLinkedScript reference an external file that contains the script code. When such a script is saved, only the path name of the external file is saved. When the script is loaded, it opens the specified file in order to access the script code.

IlBoolean IlvScript::isPersistent

(

)

const

Gets the persistence capability.

Scripts are persistent by default. Non-persistent script cannot be saved.

Returns

IlTrue if the script is persistent. Otherwise, it returns IlFalse.

See Also

setPersistent.

void IlvScript::setContents

(

const char *

contents

)

Sets the script contents.

The type of the script changes to the IlvInlineScript.

Parameters

contents

The string that will be copied and stored as the new script contents.

void IlvScript::setContentsArray	(	IlUInt	nLines,
		const char *const *	lines
	)

Sets the script contents.

Parameters

nLines	The number of strings if the array lines.
lines	The array of strings that are copied and stored as the new script contents. The type of the script changes to IlvInlineScript.

void IlvScript::setName

(

const char *

name

)

Sets the script name.

Parameters

name	The string that will be copied and stored as the new name of this script.

void IlvScript::setPathName

(

const char *

pathName

)

Sets the script path name.

Parameters

pathName

The string that will be copied and stored as the path name of the script. The type of the script changes to IlvLinkedScript.

void IlvScript::setPersistent

(

IlBoolean

persistent

)

Sets the persistence capability.

Parameters

persistent

The new persistence capability of this script.

virtual void IlvScript::write ( IlvOutputFile &  os ) const

virtual

Saves the script contents.

Parameters

os	The output file that where the script is saved.
