public static class AndroidBrushFamilySerialization

Summary

Public fields
`static @NonNull AndroidBrushFamilySerialization`	`INSTANCE`

Public methods
`static final @NonNull BrushFamily`	`decode( @NonNull InputStream input, @NonNull BrushFamilyDecodeCallback getClientTextureId )` Read a serialized `BrushFamily` from the given `InputStream` and parse it into a `BrushFamily`, throwing an exception if parsing or validation was not successful.
`static final void`	`encode( @NonNull BrushFamily brushFamily, @NonNull OutputStream output, @NonNull TextureBitmapStore textureBitmapStore )` Write a gzip-compressed `ink.proto.BrushFamily` binary proto message representing the `BrushFamily` to the given `OutputStream`.

Public methods

decode

Added in 1.0.0-alpha05

public static final @NonNull BrushFamily decode(
    @NonNull InputStream input,
    @NonNull BrushFamilyDecodeCallback getClientTextureId
)

Read a serialized BrushFamily from the given InputStream and parse it into a BrushFamily, throwing an exception if parsing or validation was not successful. Kotlin callers should use BrushFamily.Companion.decode instead.

getClientTextureId is called synchronously as part of this function call, on the same thread.

Parameters
`@NonNull InputStream input`	`InputStream` providing gzip-compressed `ink.proto.BrushFamily` binary proto messages, the same as written to `OutputStream` by `encode`.
`@NonNull BrushFamilyDecodeCallback getClientTextureId`	A callback to store the decoded texture image, if one were encoded inside the serialized `BrushFamily`, into a `TextureBitmapStore`. This is called synchronously as part of this function call on the same thread.

Returns
`@NonNull BrushFamily`	The `BrushFamily` parsed from the `InputStream`.

Throws
`java.io.IOException`	if gzip-format bytes cannot be read from `input`.
`kotlin.IllegalArgumentException`	`input` does not provide a valid `ink.proto.BrushFamily` proto message, or the corresponding `BrushFamily` is invalid.

encode

Added in 1.0.0-alpha05

public static final void encode(
    @NonNull BrushFamily brushFamily,
    @NonNull OutputStream output,
    @NonNull TextureBitmapStore textureBitmapStore
)

Write a gzip-compressed ink.proto.BrushFamily binary proto message representing the BrushFamily to the given OutputStream.

Parameters
`@NonNull BrushFamily brushFamily`	The `BrushFamily` object to encode.
`@NonNull OutputStream output`	The `OutputStream` to write the gzip-compressed encoded bytes to.
`@NonNull TextureBitmapStore textureBitmapStore`	The `TextureBitmapStore` to use to encode the texture images within the encoded `BrushFamily`. If this is not desired behavior, e.g. if the application has a static set of texture images that it includes as resources, then this can be a `TextureBitmapStore` that always returns `null`.
