Field Detail

SIGNATURES

static final byte[] SIGNATURES
Primitive signatures. Indexes match the values of IObject.Type

See Also:
IObject.Type

ELEMENT_SIZE

static final int[] ELEMENT_SIZE
Element sizes inside the array. Indexes match the values of IObject.Type

See Also:
IObject.Type

TYPE

static final java.lang.String[] TYPE
Display string of the type. Indexes match the values of IObject.Type

See Also:
IObject.Type

COMPONENT_TYPE

static final java.lang.Class<?>[] COMPONENT_TYPE
Java component type of the primitive array. Indexes match the values of {link IObject.Type}

See Also:
IObject.Type
Method Detail

getType

int getType()
Returns the IObject.Type of the primitive array.


getComponentType

java.lang.Class<?> getComponentType()
Returns the component type of the array.


getValueAt

java.lang.Object getValueAt(int index)
Returns the value of the array at the specified index

Parameters:
index - from 0 to length-1
Returns:
Byte - for a byte array Short - for a short array Integer - for an int array Long - for a long array Boolean - for a boolean array Char - for a char array Float - for a float array Double - for a double array

getValueArray

java.lang.Object getValueArray()
Get the primitive Java array. The return value can be cast into the correct component type, e.g.
 if (char.class == array.getComponentType())
 {
     char[] content = (char[]) array.getValueArray();
     System.out.println(content.length);
 }
 
The return value must not be modified because it is cached by the heap dump adapter. This method does not return a copy of the array for performance reasons.


getValueArray

java.lang.Object getValueArray(int offset,
                               int length)
Get the primitive Java array, beginning at offset and length number of elements.

The return value must not be modified because it is cached by the heap dump adapter. This method does not return a copy of the array for performance reasons.
