Constructor Detail

REXPRaw

public REXPRaw(byte[] load)

create a new raw vector with the specified payload

Parameters:

load - payload of the raw vector

REXPRaw

public REXPRaw(byte[] load,
               REXPList attr)

create a new raw vector with the specified payload and attributes

Parameters:

load - payload of the raw vector

attr - attributes for the resulting R object

Method Detail

length

public int length()

Description copied from class: REXPVector

returns the length of the vector (i.e. the number of elements)

Specified by:

length in class REXPVector

Returns:

length of the vector

isRaw

public boolean isRaw()

Description copied from class: REXP

check whether the REXP object is a raw vector

Overrides:

isRaw in class REXP

Returns:

true if the receiver is a raw vector, false otherwise

asBytes

public byte[] asBytes()

Description copied from class: REXP

returns the contents as an array of bytes (if supported by the represented object)

Overrides:

asBytes in class REXP

asNativeJavaObject

public java.lang.Object asNativeJavaObject()

Description copied from class: REXP

attempt to represent the REXP by a native Java object and return it. Note that this may lead to loss of information (e.g., factors may be returned as a string array) and attributes are ignored. Not all R types can be converted to native Java objects. Also note that R has no concept of scalars, so vectors of length 1 will always be returned as an arrays (i.e., int[1] and not Integer).

Overrides:

asNativeJavaObject in class REXP
