Value members
Concrete methods
Allocates a new buffer of {size} octets.
Allocates a new buffer of {size} octets.
- Value Params
- encoding
encoding used for call to buf.fill while initalizing
- fill
if specified, buffer will be initialized by calling buf.fill(fill). If parameter is omitted, buffer will be filled with zeros.
- size
count of octets to allocate.
Allocates a new buffer of {size} octets, leaving memory not initialized, so the contents of the newly created Buffer are unknown and may contain sensitive data.
Allocates a new buffer of {size} octets, leaving memory not initialized, so the contents of the newly created Buffer are unknown and may contain sensitive data.
- Value Params
- size
count of octets to allocate
Allocates a new non-pooled buffer of {size} octets, leaving memory not initialized, so the contents of the newly created Buffer are unknown and may contain sensitive data.
Allocates a new non-pooled buffer of {size} octets, leaving memory not initialized, so the contents of the newly created Buffer are unknown and may contain sensitive data.
- Value Params
- size
count of octets to allocate
Gives the actual byte length of a string. encoding defaults to 'utf8'. This is not the same as String.prototype.length since that returns the number of characters in a string.
Gives the actual byte length of a string. encoding defaults to 'utf8'. This is not the same as String.prototype.length since that returns the number of characters in a string.
- Value Params
- encoding
encoding used to evaluate (defaults to 'utf8')
- string
string to test.
Returns a buffer which is the result of concatenating all the buffers in the list together.
Returns a buffer which is the result of concatenating all the buffers in the list together.
If the list has no items, or if the totalLength is 0, then it returns a zero-length buffer. If the list has exactly one item, then the first item of the list is returned. If the list has more than one item, then a new Buffer is created.
- Value Params
- list
An array of Buffer objects to concatenate
- totalLength
Total length of the buffers when concatenated. If totalLength is not provided, it is read from the buffers in the list. However, this adds an additional loop to the function, so it is faster to provide the length explicitly.
When passed a reference to the .buffer property of a TypedArray instance, the newly created Buffer will share the same allocated memory as the TypedArray. The optional {byteOffset} and {length} arguments specify a memory range within the {arrayBuffer} that will be shared by the Buffer.

- Value Params
- arrayBuffer
The .buffer property of any TypedArray or a new ArrayBuffer()
Creates a new Buffer containing the given JavaScript string {str}. If provided, the {encoding} parameter identifies the character encoding. If not provided, {encoding} defaults to 'utf8'.

- data
data to create a new Buffer
Returns true if {obj} is a Buffer
Returns true if {obj} is a Buffer
- Value Params
- obj
object to test.
Returns true if {encoding} is a valid encoding argument. Valid string encodings in Node 0.12: 'ascii'|'utf8'|'utf16le'|'ucs2'(alias of 'utf16le')|'base64'|'binary'(deprecated)|'hex'

This is the number of bytes used to determine the size of pre-allocated, internal Buffer instances used for pooling. This value may be modified.
