Field Detail

seq

protected final storage.memory.MemSequenceContentI seq

Method Detail

asSequenceNode

public SequenceNode asSequenceNode()

Description copied from interface: Node

The Node's contents expressed as a Sequence. This is a shortcut for content().asSequence().

Specified by:

asSequenceNode in interface Node

Overrides:

asSequenceNode in class BareContent

isValidProperty

public boolean isValidProperty(java.lang.Object prop)

Description copied from interface: Content

Check for the validity of a given property value.

Specified by:

isValidProperty in interface Content

Parameters:

prop - the property to be checked

Returns:

true if that value can be used as a property of this Node

asSeq

public Seq asSeq()

Description copied from interface: SequenceContent

Create and return the current contents of this container as a Seq. The subtype of this Seq will depend on the type of content. e.g a type will return a ByteSeq object.

Specified by:

asSeq in interface SequenceContent

Returns:

a Seq object apprpriate to the type.

item

public Getter item(int index)
            throws IndexBoundsException

Description copied from interface: SequenceContent

Return a Getter for the item at the given index.

Specified by:

item in interface SequenceContent

Throws:

IndexBoundsException

getItem

public final java.lang.Object getItem(int index)
                               throws IndexBoundsException

Description copied from interface: SequenceContent

Return the Object at the given index.

Specified by:

getItem in interface SequenceContent

Throws:

IndexBoundsException

indexIsValid

public boolean indexIsValid(int index)

Description copied from interface: SequenceContent

Check that a given index is valid.

Specified by:

indexIsValid in interface SequenceContent

Parameters:

index - the index

Returns:

true if this is a valid point to get/set a value

range

public Getter range(int start,
                    int end)
             throws IndexBoundsException

Description copied from interface: SequenceContent

Return a Getter for the sequence of items indexed from start to end, inclusive.

The value returned by the Getter is an instance of org.nodal.util.Seq.

Specified by:

range in interface SequenceContent

Throws:

IndexBoundsException

edit

public final NodeContent.Editor edit()

Description copied from interface: Node

An Editor for changing the Content of this Node. If the Capability does not provide write access, then this will return null.

Specified by:

edit in interface Node

Specified by:

edit in class BareContent

toString

public java.lang.String toString()

editSequence

public abstract SequenceNode.Editor editSequence()

Description copied from interface: SequenceNode

Directly access SequenceEditor.

Specified by:

editSequence in interface SequenceNode

Overrides:

editSequence in class NodeFilter
