flatbuffers Builder prototype addFloat32

Initial value:

= function(value) {
  this.prep(4, 0);
  this.writeFloat32(value);
}

Add a float32 to the buffer, properly aligned, and grows the buffer (if necessary).

Parameters

{number}

value The float32 to add the the buffer.

flatbuffers Builder prototype addFloat64

Initial value:

= function(value) {
  this.prep(8, 0);
  this.writeFloat64(value);
}

Add a float64 to the buffer, properly aligned, and grows the buffer (if necessary).

Parameters

{number}

value The float64 to add the the buffer.

flatbuffers Builder prototype addInt16

Initial value:

= function(value) {
  this.prep(2, 0);
  this.writeInt16(value);
}

Add an int16 to the buffer, properly aligned, and grows the buffer (if necessary).

Parameters

{number}

value The int16 to add the the buffer.

flatbuffers Builder prototype addInt32

Initial value:

= function(value) {
  this.prep(4, 0);
  this.writeInt32(value);
}

Add an int32 to the buffer, properly aligned, and grows the buffer (if necessary).

Parameters

{number}

value The int32 to add the the buffer.

flatbuffers Builder prototype addInt64

Initial value:

= function(value) {
  this.prep(8, 0);
  this.writeInt64(value);
}

Add an int64 to the buffer, properly aligned, and grows the buffer (if necessary).

Parameters

{flatbuffers.Long}

value The int64 to add the the buffer.

flatbuffers Builder prototype addInt8

Initial value:

= function(value) {
  this.prep(1, 0);
  this.writeInt8(value);
}

Add an int8 to the buffer, properly aligned, and grows the buffer (if necessary).

Parameters

{number}

value The int8 to add the the buffer.

flatbuffers Builder prototype addOffset

Initial value:

= function(offset) {
  this.prep(flatbuffers.SIZEOF_INT, 0); 
  this.writeInt32(this.offset() - offset + flatbuffers.SIZEOF_INT);
}

Adds on offset, relative to where it will be written.

Parameters

{flatbuffers.Offset}

offset The offset to add.

flatbuffers Builder prototype asUint8Array

Initial value:

= function() {
  return this.bb.bytes().subarray(this.bb.position(), this.bb.position() + this.offset());
}

Get the bytes representing the FlatBuffer.

Only call this after you've called finish().

Returns

{Uint8Array}

flatbuffers Builder

Create a FlatBufferBuilder.

Parameters

{number=}

opt_initial_size

flatbuffers Builder prototype createLong

Initial value:

= function(low, high) {
  return flatbuffers.Long.create(low, high);
}

A helper function to avoid generated code depending on this file directly.

Parameters

{number}	low
{number}	high

Returns

{flatbuffers.Long}

flatbuffers Builder prototype createString

Encode the string s in the buffer using UTF-8.

If a Uint8Array is passed instead of a string, it is assumed to contain valid UTF-8 encoded data.

Parameters

{string|Uint8Array}

s The string to encode

Returns

{flatbuffers.Offset} The offset in the buffer where the encoded string starts

flatbuffers Builder prototype dataBuffer

Initial value:

= function() {
  return this.bb;
}

Get the ByteBuffer representing the FlatBuffer.

Only call this after you've called finish(). The actual data starts at the ByteBuffer's current position, not necessarily at 0.

Returns

{flatbuffers.ByteBuffer}

flatbuffers Builder prototype finish

Initial value:

= function(root_table, opt_file_identifier) {
  if (opt_file_identifier) {
    var file_identifier = opt_file_identifier;
    this.prep(this.minalign, flatbuffers.SIZEOF_INT +
      flatbuffers.FILE_IDENTIFIER_LENGTH);
    if (file_identifier.length != flatbuffers.FILE_IDENTIFIER_LENGTH) {
      throw new Error('FlatBuffers: file identifier must be length ' +
        flatbuffers.FILE_IDENTIFIER_LENGTH);
    }
    for (var i = flatbuffers.FILE_IDENTIFIER_LENGTH - 1; i >= 0; i--) {
      this.writeInt8(file_identifier.charCodeAt(i));
    }
  }
  this.prep(this.minalign, flatbuffers.SIZEOF_INT);
  this.addOffset(root_table);
  this.bb.setPosition(this.space);
}

Finalize a buffer, poiting to the given root_table.

Parameters

{flatbuffers.Offset}	root_table
{string=}	opt_file_identifier

flatbuffers Builder prototype forceDefaults

Initial value:

= function(forceDefaults) {
  this.force_defaults = forceDefaults;
}

In order to save space, fields that are set to their default value don't get serialized into the buffer.

Forcing defaults provides a way to manually disable this optimization.

Parameters

{boolean}

forceDefaults true always serializes default values
