Constructor & Destructor Documentation

MUserData

(

bool

deleteAfterUse

)

Construct an MUserData.

Parameters

[in]

deleteAfterUse

If true, this user data will be deleted immediately after use, instead of being cached until the owning object is deleted.

Examples:

Member Function Documentation

bool deleteAfterUse

(

)

Returns whether or not this user data should be deleted immediately after use instead of being maintained until the internal owning object is deleted.

Returns

True if this user data should be deleted after use.

void setDeleteAfterUse

(

bool

shouldDelete

)

Sets whether or not this user data should be deleted immediately after use instead of being maintained until the internal owning object is deleted.

Setting this to false may allow the data to be reused in some situations. For example, if the MUserData returned by an MPxDrawOverride instance's prepareForDraw() method has its delete-after-use set to false, then Maya will retain the data between draws of that object, passing it back to the instance for reuse on subsequent draws.

Parameters

[in]

shouldDelete

If true this user data will be deleted after use

const char * className ( )

static

Returns the name of this class.

Returns

Name of this class.
