Package de.intarsys.nativec.type

Class NativeStruct

java.lang.Object

de.intarsys.nativec.type.NativeObject

de.intarsys.nativec.type.NativeStruct

All Implemented Interfaces:

INativeObject

Direct Known Subclasses:

NativeGenericStruct, NativeStaticStruct

public abstract class NativeStruct
extends NativeObject

An abstract superclass for the implementation of structured NativeObject instances. These objects are built using named slots with other INativeObject instances (as opposed to NativeArray, using indexed slots).

Method Detail

getByteCount

public int getByteCount()

Description copied from class: NativeObject

The number of bytes occupied by this.

Specified by:

getByteCount in class NativeObject

getStructField

protected StructMember getStructField(java.lang.String name)

getStructType

public NativeStructType getStructType()

getValue

public java.lang.Object getValue()

Description copied from interface: INativeObject

A Java side representation from the memory.

Returns:

A Java side representation for the INativeObject.

setValue

public void setValue(java.lang.Object value)

Description copied from interface: INativeObject

Assign (and marshall to memory) the Java side representation.

Parameters:

value - The new Java value.

toNestedString

public java.lang.String toNestedString()

Description copied from class: NativeObject

A string for debugging purposes.

Overrides:

toNestedString in class NativeObject

Returns:

A string for debugging purposes.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
