Method Details

get

public Object get(String path)

Description copied from class: HigsonContext

Tries to resolve given path and return object from the context. If the object is not found at first try, then method is looking for objects by resolving subPath. SubPath is created by stripping given path (between first occurrence of '.' character) into first token and the rest of the path. If stripping was successful and first token is an existing object in context, then algorithm tries to use it as a subContext for the subPath. The more objects exists in depth in context, the longer it might take to resolve them.

Examples:

 HigsonContext ctx = new HigsonContext("policy.status", "AA");

 Object s1 = ctx.get("policy.status"); // found object
 Object s2 = ctx.get("policy.info");   // s2 is null here, since there is not object with this path defined in cotext

 // Sample with parent context and subContext
 HigsonContext policyCtx = new HigsonContext().set("status", "AA");
 HigsonContext ctx = new HigsonContext().set("policy", policyCtx);

 assertThat(ctx.getString("policy.status"), is("AA"));
 assertThat(ctx.getString("policy.info"), nullValue());
 assertThat(ctx.getString("user.name"), nullValue());
 

Overrides:

get in class HigsonContext

Parameters:

path - to be resolved when looking for object

Returns:

object if path was successfully resolved, otherwise null

getMapping

protected Mapping getMapping()

find

protected Object find(String field)
