date

public AbstractHttpFileBuilder date(boolean dateEnabled)

Sets whether to set the "date" header automatically. By default, the "date" header is set automatically.

isLastModifiedEnabled

protected final boolean isLastModifiedEnabled()

Sets whether to set the "content-type" header automatically based on the extension of the file.

autoDetectedContentType

public AbstractHttpFileBuilder autoDetectedContentType(boolean contentTypeAutoDetectionEnabled)

Sets whether to set the "content-type" header automatically based on the extension of the file. By default, the "content-type" header is set automatically.

entityTagFunction

protected final BiFunction<String,HttpFileAttributes,String> entityTagFunction()

Returns the function which generates the entity tag that's used for setting the "etag" header automatically.

Returns:

the etag function, or null if the "etag" header is not set automatically.

entityTag

public AbstractHttpFileBuilder entityTag(boolean enabled)

entityTag

public AbstractHttpFileBuilder entityTag(BiFunction<String,HttpFileAttributes,String> entityTagFunction)

Sets the function which generates the entity tag that's used for setting the "etag" header automatically.

Parameters:

entityTagFunction - the entity tag function that generates the entity tag, or null to disable setting the "etag" header.

buildHeaders

protected final HttpHeaders buildHeaders()

Returns the immutable additional HttpHeaders which will be set when building an HttpResponse.

addHeader

public AbstractHttpFileBuilder addHeader(CharSequence name,
                                         Object value)
