Constructor Detail

FastJsonWriter

public FastJsonWriter(StringBuilder out)

Creates a new instance that writes a JSON-encoded stream to out.

Parameters:

out - a StringBuilder object.

Method Detail

setIndent

public final void setIndent(String indent)

Sets the indentation string to be repeated for each level of indentation in the encoded document. If indent.isEmpty() the encoded document will be compact. Otherwise the encoded document will be more human-readable.

Specified by:

setIndent in interface JsonWriter

Parameters:

indent - a string containing only whitespace.

setLenient

public final void setLenient(boolean lenient)

Configure this writer to relax its syntax rules. By default, this writer only emits well-formed JSON as specified by RFC 4627. Setting the writer to lenient permits the following:

• Top-level values of any type. With strict writing, the top-level value must be an object or an array.
• Numbers may be NaNs or infinities.

Specified by:

setLenient in interface JsonWriter

Parameters:

lenient - a boolean.

isLenient

public boolean isLenient()

Returns true if this writer has relaxed syntax rules.

Returns:

a boolean.

setSerializeNulls

public final void setSerializeNulls(boolean serializeNulls)

Sets whether object members are serialized when their value is null. This has no impact on array elements. The default is true.

Specified by:

setSerializeNulls in interface JsonWriter

Parameters:

serializeNulls - a boolean.

getSerializeNulls

public final boolean getSerializeNulls()

getSerializeNulls

Returns true if object members are serialized when their value is null. This has no impact on array elements. The default is true.

Specified by:

getSerializeNulls in interface JsonWriter

Returns:

a boolean.

beginArray

public FastJsonWriter beginArray()

Begins encoding a new array. Each call to this method must be paired with a call to JsonWriter.endArray().

Specified by:

beginArray in interface JsonWriter

Returns:

this writer.

endArray

public FastJsonWriter endArray()

Ends encoding the current array.

Specified by:

endArray in interface JsonWriter

Returns:

this writer.

beginObject

public FastJsonWriter beginObject()

Begins encoding a new object. Each call to this method must be paired with a call to JsonWriter.endObject().

Specified by:

beginObject in interface JsonWriter

Returns:

this writer.

endObject

public FastJsonWriter endObject()

Ends encoding the current object.

Specified by:

endObject in interface JsonWriter

Returns:

this writer.

name

public FastJsonWriter name(String name)

Encodes the property name.

Specified by:

name in interface JsonWriter

Parameters:

name - the name of the forthcoming value. May not be null.

Returns:

this writer.

unescapeName

public FastJsonWriter unescapeName(String name)

Encodes the property name without escaping it.

Specified by:

unescapeName in interface JsonWriter

Parameters:

name - the name of the forthcoming value. May not be null.

Returns:

this writer.

value

public FastJsonWriter value(String value)

Encodes value.

Specified by:

value in interface JsonWriter

Parameters:

value - the literal string value, or null to encode a null literal.

Returns:

this writer.

unescapeValue

public FastJsonWriter unescapeValue(String value)

Encodes value without escaping it.

Specified by:

unescapeValue in interface JsonWriter

Parameters:

value - the literal string value, or null to encode a null literal.

Returns:

this writer.

nullValue

public FastJsonWriter nullValue()

Encodes null.

Specified by:

nullValue in interface JsonWriter
