Class FileByteSource

java.lang.Object

com.google.common.io.ByteSource

com.opengamma.strata.collect.io.BeanByteSource

com.opengamma.strata.collect.io.FileByteSource

All Implemented Interfaces:

Serializable, org.joda.beans.Bean, org.joda.beans.ImmutableBean

public final class FileByteSource
extends BeanByteSource
implements org.joda.beans.ImmutableBean, Serializable

A byte source implementation that obtains data from a file.

This implementation differs from Guava in that it is a Joda-Bean. In addition, BeanByteSource.read() throws UncheckedIOException instead of IOException.

Method Detail

of

public static FileByteSource of(File file)

Creates an instance based on the underlying file.

Parameters:

file - the file

Returns:

the byte source

of

public static FileByteSource of(Path path)

Creates an instance based on a file path.

Parameters:

path - the path to a file

Returns:

the byte source

metaBean

public org.joda.beans.MetaBean metaBean()

Specified by:

metaBean in interface org.joda.beans.Bean

getFileName

public Optional<String> getFileName()

Description copied from class: BeanByteSource

Gets the file name of the source.

Most sources originate from a file-based location. This is captured and returned here where available.

Overrides:

getFileName in class BeanByteSource

Returns:

the file name, empty if not known

getFile

public File getFile()

Gets the File.

Returns:

the File

openStream

public InputStream openStream()
                       throws IOException

Specified by:

openStream in class ByteSource

Throws:

IOException

sizeIfKnown

public Optional<Long> sizeIfKnown()

Overrides:

sizeIfKnown in class ByteSource

size

public long size()

Description copied from class: BeanByteSource

Gets the size of the byte source, throwing an unchecked exception.

This overrides ByteSource to throw UncheckedIOException instead of IOException.

Overrides:

size in class BeanByteSource

load

public ArrayByteSource load()

Description copied from class: BeanByteSource

Loads the content of the byte source into memory.

Overrides:

load in class BeanByteSource

Returns:

the byte array

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
