## ShaderArrayParamDef.ItemDef2

### Introduced

v11.0 (2013)

### Description

Returns the underlying ShaderParamDef or ShaderStructParamDef object for this array item. This method is similar to ShaderArrayParamDef.ItemDef but specific to the Python language.

### C# Syntax

    // get accessor
    Object rtn = ShaderArrayParamDef.ItemDef2;

### Examples

#### Python Example

    #
    # This example goes through the list of shader definitions in Softimage,
    # looks for arrays of structures and prints the parameter names as well
    # as the ProgID of the owning shader definition
    #
    from siutils import *
    si = si()
    si.NewScene("", 0)
    for shaderdef in si.ShaderDefinitions :
            for paramdef in shaderdef.InputParamDefs.Definitions :
                    if paramdef.IsArray :
                            underlying = paramdef.ItemDef2
                            if underlying.IsStructure :
                                    log("Found an array of structures for %s in %s" % (paramdef.Name, shaderdef.ProgID))
    # Expected results:
    # INFO : Found an array of structures for lights in Softimage.material-phong.1.0
    # INFO : Found an array of structures for lights in Softimage.material-lambert.1.0
