Class Base64.Builder

java.lang.Object

org.apache.commons.codec.binary.BaseNCodec.AbstractBuilder<Base64, Base64.Builder>

org.apache.commons.codec.binary.Base64.Builder

All Implemented Interfaces:

Supplier<Base64>

Enclosing class:

Base64

public static class Base64.Builder
extends BaseNCodec.AbstractBuilder<Base64, Base64.Builder>

Builds Base64 instances.

To configure a new instance, use a Base64.Builder. For example:

Base64 base64 = Base64.builder()
  .setCodecPolicy(CodecPolicy.LENIENT)       // default is lenient, null resets to default
  .setEncodeTable(customEncodeTable)         // default is built in, null resets to default
  .setLineLength(0)                          // default is none
  .setLineSeparator('\r', '\n')              // default is CR LF, null resets to default
  .setPadding('=')                           // default is '='
  .setUrlSafe(false)                         // default is false
  .get()

Method Details

get

public Base64 get()

setDecodeTableFormat

public Base64.Builder setDecodeTableFormat(Base64.DecodeTableFormat format)

Sets the format of the decoding table. This method allows to explicitly state whether a standard or URL-safe Base64 decoding is expected. This method does not modify behavior on encoding operations. For configuration of the encoding behavior, please use setUrlSafe(boolean) method.

By default, the implementation uses the Base64.DecodeTableFormat.MIXED approach, allowing a seamless handling of both Base64.DecodeTableFormat.URL_SAFE and Base64.DecodeTableFormat.STANDARD base64.

Parameters:

format - table format to be used on Base64 decoding. Use Base64.DecodeTableFormat.MIXED or null to reset to the default behavior.

Returns:

this instance.

setEncodeTable

public Base64.Builder setEncodeTable(byte... encodeTable)

Description copied from class: BaseNCodec.AbstractBuilder

Sets the encode table.

Overrides:

setEncodeTable in class BaseNCodec.AbstractBuilder<Base64, Base64.Builder>

Parameters:

encodeTable - the encode table, null resets to the default.

Returns:

this instance.

setUrlSafe

public Base64.Builder setUrlSafe(boolean urlSafe)

Sets the URL-safe encoding policy.

This method does not modify behavior on decoding operations. For configuration of the decoding behavior, please use Builder.setDecodeTableFormat(DecodeTableFormat) method.

Parameters:

urlSafe - URL-safe encoding policy, null resets to the default.

Returns:

this instance.
