Method Detail

add

ColumnNameBuilder add(java.nio.ByteBuffer bb)

Add a new ByteBuffer as the next component for this name.

Parameters:

bb - the ByteBuffer to add

Returns the number of component already added to this builder.

Returns:

the number of component in this Builder

remainingCount

int remainingCount()

Returns:

the maximum number of component that can still be added to this Builder

get

java.nio.ByteBuffer get(int idx)

Returns:

the ith component in this builder.

build

java.nio.ByteBuffer build()

Build the column name.

Returns:

the built column name

buildAsEndOfRange

java.nio.ByteBuffer buildAsEndOfRange()

Build the column name so that the result sorts at the end of the range represented by this (uncomplete) column name.

Throws:

java.lang.IllegalStateException - if the builder is empty or full.

buildForRelation

java.nio.ByteBuffer buildForRelation(Relation.Type op)

copy

ColumnNameBuilder copy()

Clone this builder.

Returns:

the cloned builder.

getComponent

java.nio.ByteBuffer getComponent(int i)

Returns the ith component added to this builder.

Parameters:

i - the component to return

Returns:

the ith component added to this builder.

Throws:

java.lang.IllegalArgumentException - if i >= componentCount().
