Method Detail

getTypeCode

public int getTypeCode()

Description copied from class: PackratDatatype

Return a single-byte code for the type. Must be unique. Valid codes are defined in PackratConstants.

Specified by:

getTypeCode in class PackratDatatype

getTypeDescription

public java.lang.String getTypeDescription()

Description copied from class: PackratDatatype

Return a String description of the data type (e.g. "String", "UInt16", etc.)

Specified by:

getTypeDescription in class PackratDatatype

isFixedSize

public boolean isFixedSize()

Description copied from class: PackratDatatype

If true, datatype requires a fixed number of bytes.

Specified by:

isFixedSize in class PackratDatatype

objectToBytes

public void objectToBytes(java.lang.Object input,
                          ByteBuffer output)

Description copied from class: PackratDatatype

Convert the given object to its binary representation. Throws IllegalArgumentException if it doesn't like the input.

Specified by:

objectToBytes in class PackratDatatype

bytesToObject

public java.lang.Object bytesToObject(ByteBuffer input)

Description copied from class: PackratDatatype

Convert the given bytes to an appropriate object representation. Throws IllegalArgumentException if it doesn't like the input.

Specified by:

bytesToObject in class PackratDatatype

viewFileAsList

public java.util.List viewFileAsList(PackratRandomAccessReader filet)
                              throws java.io.IOException

Throws:

java.io.IOException

getContentsType

public PackratDatatype getContentsType()

setContentsType

public void setContentsType(PackratDatatype newType)

getSubtypes

public PackratDatatype[] getSubtypes()

Description copied from class: PackratDatatype

Return a list of any subtypes. Defaults to an empty array. Subtypes are any datatypes that are part of this type - for example, fields in a structure or values in a list.

Overrides:
