Method Detail

setNull

void setNull(int index)

Sets the token at the specified position to be null valued.

Parameters:

index - the position of the token in the array

setNull

void setNull(int start,
             int length)

Sets the tokens in the specified subsequence to be null valued.

Parameters:

start - the starting index of the subsequence in the array

length - the length of the subsequence

setZero

void setZero(int index)

Sets the token at the specified position to be zero valued.

Parameters:

index - the position of the token in the array

setZero

void setZero(int start,
             int length)

Sets the tokens in the specified subsequence to be zero valued.

Parameters:

start - the starting index of the subsequence in the array

length - the length of the subsequence

setValue

void setValue(int index,
              TokenValued value)

Sets the token at the specified position to the given value.

Parameters:

index - the position of the token in the array

value - the value to which to set the token. This value must be of an appropriate type for the array.

fillValue

void fillValue(int start,
               int length,
               TokenValued value)

Sets the tokens in the specified subsequence to the given value.

Parameters:

start - the starting index of the subsequence in the array

length - the length of the subsequence

value - the value to which to set the tokens. This value must be of an appropriate type for the array

setValues

void setValues(int start,
               TokenSequence values,
               int offset,
               int length)

Sets the tokens in the specified subsequence of the array to the corresponding values from a subsequence of the given source sequence.

Parameters:

start - the starting index of the subsequence in the array

values - the source sequence. This sequence must be of an appropriate type for the array.

offset - the starting index in the source sequence. Corresponding values will be taken relative to this position. That is, the value of the token at position offset in values will be assigned to the token at position start, and so on.

length - the number of tokens to copy

appendZero

void appendZero()

Appends a zero value to this sequence.

appendZero

void appendZero(int count)

Appends the specified number of zero values to this sequence.

Parameters:

count - the number of zero values to append

appendNull

void appendNull()

Appends a null value to this sequence.

appendNull

void appendNull(int count)

Appends the specified number of null values to this sequence.

Parameters:

count - the number of null values to append

reset

void reset()

Removes all elements from the sequence.

getTokenSetter

TokenSettable getTokenSetter(int index)

Returns a mutator for the given index.

Parameters:

index - the position

Returns:

a mutator for the given index.
