Constructor Detail

Table

public Table()

Method Detail

getByteBuffer

public java.nio.ByteBuffer getByteBuffer()

Get the underlying ByteBuffer.

Returns:

Returns the Table's ByteBuffer.

__offset

protected int __offset(int vtable_offset)

Look up a field in the vtable.

Parameters:

vtable_offset - An `int` offset to the vtable in the Table's ByteBuffer.

Returns:

Returns an offset into the object, or `0` if the field is not present.

__offset

protected static int __offset(int vtable_offset,
                              int offset,
                              java.nio.ByteBuffer bb)

__indirect

protected int __indirect(int offset)

Retrieve a relative offset.

Parameters:

offset - An `int` index into the Table's ByteBuffer containing the relative offset.

Returns:

Returns the relative offset stored at `offset`.

__indirect

protected static int __indirect(int offset,
                                java.nio.ByteBuffer bb)

__string

protected java.lang.String __string(int offset)

Create a Java `String` from UTF-8 data stored inside the FlatBuffer. This allocates a new string and converts to wide chars upon each access, which is not very efficient. Instead, each FlatBuffer string also comes with an accessor based on __vector_as_bytebuffer below, which is much more efficient, assuming your Java program can handle UTF-8 data directly.

Parameters:

offset - An `int` index into the Table's ByteBuffer.

Returns:

Returns a `String` from the data stored inside the FlatBuffer at `offset`.

__vector_len

protected int __vector_len(int offset)

Get the length of a vector.

Parameters:

offset - An `int` index into the Table's ByteBuffer.

Returns:

Returns the length of the vector whose offset is stored at `offset`.

__vector

protected int __vector(int offset)

Get the start data of a vector.

Parameters:

offset - An `int` index into the Table's ByteBuffer.

Returns:

Returns the start of the vector data whose offset is stored at `offset`.

__vector_as_bytebuffer

protected java.nio.ByteBuffer __vector_as_bytebuffer(int vector_offset,
                                                     int elem_size)

Get a whole vector as a ByteBuffer. This is efficient, since it only allocates a new ByteBuffer object, but does not actually copy the data, it still refers to the same bytes as the original ByteBuffer. Also useful with nested FlatBuffers, etc.

Parameters:

vector_offset - The position of the vector in the byte buffer

elem_size - The size of each element in the array

Returns:

The ByteBuffer for the array

__vector_in_bytebuffer

protected java.nio.ByteBuffer __vector_in_bytebuffer(java.nio.ByteBuffer bb,
                                                     int vector_offset,
                                                     int elem_size)

Initialize vector as a ByteBuffer. This is more efficient than using duplicate, since it doesn't copy the data nor allocattes a new ByteBuffer, creating no garbage to be collected.

Parameters:

bb - The ByteBuffer for the array

vector_offset - The position of the vector in the byte buffer

elem_size - The size of each element in the array

Returns:

The ByteBuffer for the array

__union

protected Table __union(Table t,
                        int offset)

Initialize any Table-derived type to point to the union at the given `offset`.

Parameters:

t - A `Table`-derived type that should point to the union at `offset`.

offset - An `int` index into the Table's ByteBuffer.

Returns:

Returns the Table that points to the union at `offset`.

__has_identifier

protected static boolean __has_identifier(java.nio.ByteBuffer bb,
                                          java.lang.String ident)

Check if a ByteBuffer contains a file identifier.

Parameters:

bb - A ByteBuffer to check if it contains the identifier `ident`.

ident - A `String` identifier of the FlatBuffer file.

Returns:

True if the buffer contains the file identifier

sortTables

protected void sortTables(int[] offsets,
                          java.nio.ByteBuffer bb)

Sort tables by the key.

Parameters:

offsets - An 'int' indexes of the tables into the bb.

bb - A ByteBuffer to get the tables.

keysCompare

protected int keysCompare(java.lang.Integer o1,
                          java.lang.Integer o2,
                          java.nio.ByteBuffer bb)

Compare two tables by the key.

Parameters:

o1 - An 'Integer' index of the first key into the bb.

o2 - An 'Integer' index of the second key into the bb.

bb - A ByteBuffer to get the keys.

compareStrings

protected static int compareStrings(int offset_1,
                                    int offset_2,
                                    java.nio.ByteBuffer bb)

Compare two strings in the buffer.

Parameters:

offset_1 - An 'int' index of the first string into the bb.

offset_2 - An 'int' index of the second string into the bb.

bb - A ByteBuffer to get the strings.

compareStrings

protected static int compareStrings(int offset_1,
                                    byte[] key,
                                    java.nio.ByteBuffer bb)

Compare string from the buffer with the 'String' object.

Parameters:

offset_1 - An 'int' index of the first string into the bb.

key - Second string as a byte array.

bb - A ByteBuffer to get the first string.

__reset

public void __reset()

Resets the internal state with a null ByteBuffer and a zero position. This method exists primarily to allow recycling Table instances without risking memory leaks due to ByteBuffer references. The instance will be unusable until it is assigned again to a ByteBuffer.
