extends Object
Class Inheritance
Type Parameters
<E>
the exception type that can be thrown by the expansion function
Imports
io.smallrye.common.function.ExceptionBiConsumer
The expression resolve context, which can be used to query the current expression key, write out expansions or default values, or perform validation.

The expression context is not thread-safe and is not valid outside of the property expansion function body.

Method Detail

emitToBuilderback to summary
private void emitToBuilder(final StringBuilder target, final Node node) throws ResolveContext:E
expandDefaultback to summary
public void expandDefault(StringBuilder target) throws ResolveContext:E

Expand the default value to the given string builder. If the default value contains an expression, it will have been expanded unless Expression.Flag#NO_RECURSE_DEFAULT was given. The result is not cached and will be re-expanded every time this method is called.

Parameters
target:StringBuilder

the string builder target

Exceptions
ResolveContext:E:
if the recursive expansion threw an exception
expandDefaultback to summary
public void expandDefault() throws ResolveContext:E

Expand the default value to the current target string builder. If the default value contains an expression, it will have been expanded unless Expression.Flag#NO_RECURSE_DEFAULT was given. The result is not cached and will be re-expanded every time this method is called.

Exceptions
ResolveContext:E:
if the recursive expansion threw an exception
getExpandedDefaultback to summary
public String getExpandedDefault() throws ResolveContext:E

Expand the default value to a string. If the default value contains an expression, it will have been expanded unless Expression.Flag#NO_RECURSE_DEFAULT was given. The result is not cached and will be re-expanded every time this method is called.

Returns:String

the expanded string (not null)

Exceptions
ResolveContext:E:
if the recursive expansion threw an exception
getKeyback to summary
public String getKey() throws ResolveContext:E

Get the expression resolution key, as a string. If the key contains an expression, it will have been expanded unless Expression.Flag#NO_RECURSE_KEY was given. The result is not cached and will be re-expanded every time this method is called.

Returns:String

the expanded key (not null)

Exceptions

if the recursive expansion threw an exception

pack-priv StringBuilder getStringBuilder()
hasDefaultback to summary
public boolean hasDefault()

Determine if the current expression has a default value.

Returns:boolean

true if there is a default value, false otherwise
