Constructor Detail

IntsRefBuilder

public IntsRefBuilder()

Sole constructor.

Method Detail

ints

public int[] ints()

Return a reference to the ints of this builder.

length

public int length()

Return the number of ints in this buffer.

setLength

public void setLength(int length)

Set the length.

clear

public void clear()

Empty this builder.

intAt

public int intAt(int offset)

Return the int at the given offset.

setIntAt

public void setIntAt(int offset,
                     int b)

Set an int.

append

public void append(int i)

Append the provided int to this buffer.

grow

public void grow(int newLength)

Used to grow the reference array.

In general this should not be used as it does not take the offset into account.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

copyInts

public void copyInts(int[] otherInts,
                     int otherOffset,
                     int otherLength)

Copies the given array into this instance.

copyInts

public void copyInts(IntsRef ints)

Copies the given array into this instance.

copyUTF8Bytes

public void copyUTF8Bytes(BytesRef bytes)

Copy the given UTF-8 bytes into this builder. Works as if the bytes were first converted from UTF-8 to UTF-32 and then copied into this builder.

get

public IntsRef get()

Return a IntsRef that points to the internal content of this builder. Any update to the content of this builder might invalidate the provided ref and vice-versa.

toIntsRef

public IntsRef toIntsRef()

Build a new CharsRef that has the same content as this builder.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
