Method Detail

indexFrom

protected final int indexFrom(CharSequence name)

isValidIndex

protected final boolean isValidIndex(int index)

size

public int size()

Description copied from interface: Array

Return the number of name-value fields in this object.

Specified by:

size in interface Array

Returns:

the number of name-value fields; never negative

isEmpty

public boolean isEmpty()

Description copied from interface: Array

Return whether this document contains no fields and is therefore empty.

Specified by:

isEmpty in interface Array

Returns:

true if there are no fields in this document, or false if there is at least one.

compareTo

public int compareTo(Array that)

Specified by:

compareTo in interface Comparable<Array>

iterator

public Iterator<Array.Entry> iterator()

Specified by:

iterator in interface Iterable<Array.Entry>

remove

public Value remove(int index)

Description copied from interface: Array

Remove the specified entry from this array

Specified by:

remove in interface Array

Parameters:

index - the index

Returns:

the value in the removed entry, or null if there is no such entry

removeAll

public Array removeAll()

Description copied from interface: Array

Remove all entries from this array.

Specified by:

removeAll in interface Array

Returns:

this array to allow for chaining methods

has

public boolean has(int index)

Description copied from interface: Array

Determine if this contains an entry at the given index.

Specified by:

has in interface Array

Parameters:

index - the index

Returns:

true if the entry exists, or false otherwise

get

public Value get(int index)

Description copied from interface: Array

Gets the value in this array at the given index.

Specified by:

get in interface Array

Parameters:

index - the index

Returns:

The field value, if found, or null otherwise

setValue

public Array setValue(int index,
                      Value value)

Description copied from interface: Array

Set the value for the field with the given name to be a value.

Specified by:

setValue in interface Array

Parameters:

index - the index of the field; must be greater than or equal to 0 and less than or equal to size

value - the new value

Returns:

this array to allow for chaining methods

expand

public Array expand(int desiredSize,
                    Value value)

Description copied from interface: Array

If the current size of the array is smaller than the given size, expand it and use the supplied value for all new entries. This method does nothing if the current size is larger than the supplied desiredSize.

Specified by:

expand in interface Array

Parameters:

desiredSize - the desired size of the array; may be negative

value - the new value for any new entries

Returns:

this array to allow for chaining methods

increment

public Array increment(int index,
                       Value increment)

Description copied from interface: Array

Increment the numeric value at the given location by the designated amount.

Specified by:

increment in interface Array

Parameters:

index - the index of the field; must be greater than or equal to 0 and less than or equal to size

increment - the amount to increment the existing value; may be negative to decrement

Returns:

this array to allow for chaining methods

add

public Array add(Value value)

Description copied from interface: Array

Adds the value to the end of this array.

Specified by:

add in interface Array
