Field Detail

value

protected PVStructure[] value

structureArray

protected StructureArray structureArray

Constructor Detail

BasePVStructureArray

public BasePVStructureArray(StructureArray structureArray)

Constructor.

Parameters:

structureArray - The Introspection interface.

Method Detail

getStructureArray

public StructureArray getStructureArray()

Description copied from interface: PVStructureArray

Get the introspection interface.

Specified by:

getStructureArray in interface PVStructureArray

Returns:

The interface.

allocate

protected void allocate(int newCapacity)

Specified by:

allocate in class AbstractPVArray

getValue

protected Object getValue()

Specified by:

getValue in class AbstractPVArray

setValue

protected void setValue(Object array)

Specified by:

setValue in class AbstractPVArray

get

public int get(int offset,
               int len,
               StructureArrayData data)

Description copied from interface: PVStructureArray

Get values from a PVDoubleArray and put them into double[]to

Specified by:

get in interface PVStructureArray

Parameters:

offset - the offset to the first element to get

len - the maximum number of elements to transfer

data - the class containing the data and an offset into the data. Get sets these values. The caller must do the actual data transfer.

Returns:

the number of elements that can be transfered. This is always less than or equal to length. If the value is less then length then get should be called again. If the return value is greater than 0 then data.data is a reference to the array and data.offset is the offset into the array.

put

public int put(int offset,
               int len,
               PVStructure[] from,
               int fromOffset)

Description copied from interface: PVStructureArray

Put values into a PVStructureArray from PVStructure[]from

Specified by:

put in interface PVStructureArray

Parameters:

offset - the offset to the first element to put

len - the maximum number of elements to transfer

from - the array from which to get the data

fromOffset - the offset into from

Returns:

the number of elements transfered. This is always less than or equal to length. If the value is less than the length then put should be called again.

shareData

public void shareData(PVStructure[] from)

Description copied from interface: PVStructureArray

Share the data from caller. The capacity and length are taken from the array and this array is made immutable. This should only be used to share immutable data.

Specified by:

shareData in interface PVStructureArray

Parameters:

from - the data to share

valueEquals

protected boolean valueEquals(Object obj)

Specified by:

valueEquals in class AbstractPVArray

getAt

protected Serializable getAt(int index)

Specified by:

getAt in class AbstractPVComplexArray

setAt

protected void setAt(int index,
                     Serializable obj)

Specified by:

setAt in class AbstractPVComplexArray

createNewInstance

protected Serializable createNewInstance()

Specified by:

createNewInstance in class AbstractPVComplexArray

hashCode

public int hashCode()

Overrides:

hashCode in class Object
