Constructor Detail

PsArray

public PsArray(Object[] value,
               boolean executable)

Constructor.

Parameters:

value - The value to encapsulate.

executable - Set to true if this object is executable.

Method Detail

duplicate

public PsObject duplicate()

Description copied from interface: PsObject

This is a shallow copy. Specifically, composite objects should generally return themselves. Simple objects should return copies of themselves.

Returns:

A duplicate of this that conforms to what is expected by the "dup" operator.

isComposite

public boolean isComposite()

Description copied from interface: PsObject

The method should be overridden by composite objects.

Returns:

True iff this object is a composite PostScript object.

isExecutable

public boolean isExecutable()

Description copied from interface: PsObject

Indicates whether this object is executable.

Returns:

True iff this object is executable.

isComparable

public boolean isComparable(PsObject object)

Description copied from interface: PsObject

Test the comparability of two PSObjects. Used in the eq, ne, lt, etc. operators.

Parameters:

object - The object that should be tested for comparability.

Returns:

True if this is comparable to object, false otherwise.

getTypeName

public PsName getTypeName()

Description copied from interface: PsObject

Needed for the "type" operator.

Returns:

The type name as defined in PSRM2, Chapter 8, "type" operator.

size

public int size()

Return the size of this array.

Returns:

The size of this array.

get

public PsObject get(int index)

Return one item from the array.

Parameters:

index - The index to the array item.

Returns:

The requested array item.

set

public void set(int index,
                Object object)

Sets the value of one item in the array.

Parameters:

index - The index to the array item.

object - The object which should be set at the array location for index.

convertToMatrix

public PsMatrix convertToMatrix()

Attempts to convert this into a PsMatrix instance.

Returns:

A new PsMatrix instance made from this, or null if not possible.

setExecutable

public void setExecutable(boolean executable)

Sets the executable status of this array.

Parameters:

executable - The status to set.
