Class Accessor

All Implemented Interfaces:

XMLStructure

public class Accessor
extends ColladaElement

Collada Accessor nodes provide access to some data array, like a FloatArray or an IntArray. The actual type of the accessor is determined from the type of its array. We assume that parameters have the same type. The data array must first be "resolved" before it can be accessed, by calling the resolve() method.

Accessor

Default constructor

Accessor

         throws IOException

Constructor used to create an Accessor Object from XML

IOException

Method Detail

resolve

public void resolve()

method that should be called in order to resolve the source data array, before the accessor can be used to actually access data.

getNrOfNamedParams

public int getNrOfNamedParams()

Returns the number of named parameters for this Accessor

calcTmpVars

private void calcTmpVars(String[] fieldNames)

getHomogeneousFloatData

public float[] getHomogeneousFloatData(String[] fieldNames)

returns the float data from from the Collada FloatArray in a Java float array. The number of floats equals the number of (named) parameters times the "count" attribute of this accessor. The FloatArray is accessed in accordance with the offset and stride attributes of this Accessor; No such offset and stride apply to the destination, i.e. the result is a simple, homogeneous array of consecutive data. If the result turns out to be an exact copy of the floats FloatArray, a reference to the floats array of the latter is returned. Otherwise, a new float array is allocated, and the requied data is copied.

getHomogeneousFloatData

public float[] getHomogeneousFloatData()

Like getHomogeneousFloatData(null);

getHomogeneousIntData

public int[] getHomogeneousIntData(String[] fieldNames)

Like getHomogeneousFloatData, but accesses IntArray data.

getHomogeneousBoolData

public boolean[] getHomogeneousBoolData(String[] fieldNames)

Like getHomogeneousFloatData, but accesses BoolArray data.

getHomogeneousBoolData

public boolean[] getHomogeneousBoolData()

Like getHomogeneousFloatData, but accesses BoolArray data.

getHomogeneousNameData

public String[] getHomogeneousNameData(String[] fieldNames)

Like getHomogeneousFloatData, but accesses NameArray data.

getHomogeneousNameData

public String[] getHomogeneousNameData()

Like getHomogeneousFloatData, but accesses NameArray data.

getHomogeneousIDREFData

public String[] getHomogeneousIDREFData(String[] fieldNames)

Like getHomogeneousFloatData, but accesses IDREFArray data.

getHomogeneousIDREFData

public String[] getHomogeneousIDREFData()

Like getHomogeneousFloatData, but accesses IDREFArray data.

getFieldOffset

private int getFieldOffset(String fieldName)

getFieldSize

private int getFieldSize(String fieldName)

getFieldOffsets

private int[] getFieldOffsets(String[] fieldNames)

getFieldSizes

appendAttributes

public StringBuilder appendAttributes(StringBuilder buf)

Description copied from class: XMLStructureAdapter

Appends a String to buf that encodes the contents for the XML encoding. MUST BE OVERWRITTEN BY IMPLEMENTATIONS. (The default implementation appends nothing). The encoding should start on a new line, using indentation equal to tab. There should be no newline after the encoding.

Overrides:

appendContent in class XMLStructureAdapter

                   throws IOException

Description copied from class: XMLStructureAdapter

Overrides:

decodeContent in class XMLStructureAdapter

Throws:

IOException

xmlTag

public static String xmlTag()

getXMLTag

public String getXMLTag()

returns the XML Stag for XML encoding

Specified by:

getXMLTag in interface XMLStructure

Overrides:

getXMLTag in class XMLStructureAdapter
