Public methods
`Dumper`	`@CanIgnoreReturnValue add(Dumper.Dumpable object)`

`Dumper`	`@CanIgnoreReturnValue add(String field, byte[] value)`
`Dumper`	`@CanIgnoreReturnValue addIfNonDefault( String field, @Nullable Object value, @Nullable Object defaultValue )` Calls `add` if `value` is not equal to `defaultValue`.
`Dumper`	`@CanIgnoreReturnValue <T> addIfNonDefault( String field, T value, T defaultValue, Function<T, Object> valueTransformFunction )` Applies `valueTransformFunction` to `value` and `defaultValue` and passes the results to `addIfNonDefault`.

Public methods

add

@CanIgnoreReturnValue
public Dumper add(Dumper.Dumpable object)

add

@CanIgnoreReturnValue
public Dumper add(String field, Object value)

add

@CanIgnoreReturnValue
public Dumper add(String field, byte[] value)

addIfNonDefault

@CanIgnoreReturnValue
public Dumper addIfNonDefault(
    String field,
    @Nullable Object value,
    @Nullable Object defaultValue
)

Calls add if value is not equal to defaultValue.

It is not permitted to pass a null value to add, so null is only permitted here as a default value. Passing value == null && defaultValue != null will result in a NullPointerException.

addIfNonDefault

@CanIgnoreReturnValue
public Dumper <T> addIfNonDefault(
    String field,
    T value,
    T defaultValue,
    Function<T, Object> valueTransformFunction
)

Applies valueTransformFunction to value and defaultValue and passes the results to addIfNonDefault.

See addIfNonDefault for limitations around when null results from valueTransformFunction are permitted.

addTime

@CanIgnoreReturnValue
public Dumper addTime(String field, long time)

endBlock

@CanIgnoreReturnValue
public Dumper endBlock()

startBlock

@CanIgnoreReturnValue
public Dumper startBlock(String name)

toString

public String toString()
