SArray

public SArray()

Method Detail

size

public int size()

Description copied from interface: SA

the size of the array

Specified by:

size in interface SA

Returns:

the total number of values in the array

get

public SV get(int index)

Description copied from interface: SA

The value stored at index.

Specified by:

get in interface SA

Parameters:

index - the index of the value to be retrieved.

Returns:

the retrieved value.

set

public void set(int index,
                SV val)

Description copied from interface: SA

Changes the value at a particular index

Specified by:

set in interface SA

Parameters:

index - the index where the value is to be saved

val - the value to be saved

add

public void add(SV val)

Description copied from interface: SA

Adds a new value to the end of the array

Specified by:

add in interface SA

Parameters:

val - the new value

insert

public void insert(int index,
                   SV val)

Description copied from interface: SA

Inserts a value into the array at the specified index. All values with equal or greater index are moved up one and the array is enlarged by 1.

Specified by:

insert in interface SA

Parameters:

index - the location where the new value is to be inserted.

val - the new value

insert

public void insert(int index,
                   SA vals)

Description copied from interface: SA

Inserts a bunch of values into the array. The array is extended by vals.size(), all elements at index or greater are moved up by vals.size() and the new values are copied into the array starting at index.

Specified by:

insert in interface SA

Parameters:

index - the location in the array where the

vals - the new values to be inserted

delete

public void delete(int index)

Description copied from interface: SA

Removes a value from the array. All elements with a greater index are moved down 1. If the array size cannot be changed, a null value can be inserted at the end.

Specified by:

delete in interface SA

Parameters:

index - the location of the value to be removed.

delete

public void delete(int first,
                   int last)

Description copied from interface: SA

Removes a sequence of values from the array. All elements with a greater index than last are moved down. If the array size cannot be changed, null values are inserted at the end.

Specified by:

delete in interface SA

Parameters:

first - the index of the first value to be removed.

last - the index of the last value to be removed.

extract

public SA extract(int first,
                  int last)

Description copied from interface: SA

Functions the same as delete except that the values to be deleted are first copied out of the array and then returned as an array.

Specified by:

extract in interface SA

Parameters:

first - the index of the first value to be removed.

last - the index of the last value to be removed.

Returns:

an array of the values that were deleted.

myParent

public SParented myParent()

Description copied from interface: SParented

Returns the parent of this object, if this object is part of a tree. This has been named so as not to interfere with the get/set method patterns used by SOReflect

Specified by:

myParent in interface SParented

Returns:

the parent object.

newParent

public void newParent(SParented newParent)

Description copied from interface: SParented

changes the parent of this object. This has been named so as not to interfere with the get/set method patterns used by SObjReflect.

Specified by:
